LAWN SPRINKLER,

,'-inlion is to ha? asseniblzwe a novel Serial No. 192,337.

i i s. The end or each hranch pipe 12 thu-ed as 241, anc a orresponzlinw f shaped interior Zone 25 orined in nd 26 which A spring screws into h l the ltlaring end ne ria 2T abuts one end again,y 24: of the pipe 12 and at its opposite end ments.

The nature ol my invention and tinguishing features ani clearly :appear as the lese@ Reference to be had to ing drawings .torni i heat-ion, it being understood that ings are merely illustrative o one ot the invention.

Figure 1 is a central vertical section et a sprinkler embodying my invention, and

Figure 2 is a transverse. vertical section as indicated hy the line 2-2 in Figure 1.

In carrying out my invention in accordance with the illustrated example, a tubular vertical pipe element 10 is provided havin@ suitable supporting means, suf-.h as a stand 1.1. Above the pipe 10 are lateral branch pipes 12 which connnunica with said pipe element 10 through a hollow cap 1? At the outer end of each lateral branch pipe 12 is a head 14 which connnunicates 'with short tubular members 15 earh l g to a head 1G having at one end internal thrcaos 17 with v-,uiich connects the threaded tubular stein 18 of a sprayer nozzle 1S) the outer end olf which has an opening` 20 Within which opening there is disposed in the sprayer nozzle 19 a spreader head 21 on a stein 121 which at the end opposite the head is Vfitted tightly in the end et the head 16 or fastener lo said iead in any suitable manner. mnh nut 22 is provided on the threaded. tuoular stein 18 to bind against the head 16 ifor holding the nozzle 19 in adjusted relation to said head. The head 16 is disposed in accordance with the reaction principle for turning the lateral branch pipes 12 about the axis of the vertical pipe element 10. About the stein 121 of spreader 21 coiled a spring 23 which exerts its pressure at one end against the closed end of lthe head 16 and at the opposite end against the tubular stein its and the correspondingly shaped 1V). The bular inen'iber is screwed i Lipper end into the head and the lower end ol' said dement is flared, as at 29, and bears against a correspondingly shaped sono in a gland or bonnet on head 141-. Ai coil spr-.ing 31 exerts its pressure againsty the flaring end 29 to iform a Water tight conu'ith the bonnet 30.

t A sleeve 32 is provided at the upper end et tubular element 10 and ii-xtenes above the same suiliciently 'to ei'llect a threaded connection thereof with the cap 13 so thai said cap and sleeve 32 may turn xvi th the branches 12 about the anis oit pipe element 10. The sleeve 32 is formed With an internal up- Wardly facing shoulder 33 above which are resilient packing rings 34. A collar is provided on the pipe element 10 at ghe top and heneaflh the same a Wasl'ier 3G may he employed, disposed on 1die uppermost one of the packing rings 34. A downwardly facing shoulder 2S formed on ihc sleeve 32 against which bears the upper end oi' a coil spring 37. On said spring at the lower end is a lateral arm 39 forming a :linger hold whereby said spring 37 may be stressed. 0n the pipe element 10 at the base is a Zone or enlarged diameter termed with a notch 10, the lower end of which is inclined to give -a cam action. By grasping the arm 39 and turning the same la erally, said arui 39 may le moved out oli notch el() and into Contact with the inclined surface at the bottom of said notch, which thereby will exert a compressive action on the spring, increasing its tension, so that it Will bear with greater pressure on the shoulder 38 for the purpose of holding the sleeve 32 against turning, and thereby preventing the turning of the head 14 and branch pipes 12 with the head 16 of the latter.

The numeral 4l indicates an inlet for embodiment of mv invention, l do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied Without departure from the spirit of the invention as defined in the appended claim.

I claim:

An assemblage of 'the class described, including a vertical pipe formed with a notch at the exterior, a sleeve on said pipe, branch pipes in communication with the first mentioned pipe, means on said sleeve carrying` said branch pipes, and a coil spring exertu ing pressureendwise against said sleeve and against said vertical pipe at the notch, said spring having a lateral arm movable into or out ofthe notch and the bottom of the notch affording an incline to cause increased pressure of the spring` when moved up said incline to a level above the lower end of the incline.
